To all whom t may concer/n.: f

Be it known that l, CHARLES Si.y Mo- (hxn'riir, Jr., am ay citizen ofthe United States, residing atSandusliy, inl the county oll Erie andState or Ohio, havek invented certain new and useful f Improvements inlslot r Cultivators7 of which the following is specification. i "lheinvention 'hereof appertains to the art ot motor driven agriculturalmachinery, and the speci altj/pe otimplenient ycomprising theimprovements oit the invention consists ot a motor driven wheeledcultivatoi.` l

The cultivator emhodiedin this invention primarily designed toi' thecultivation ot truck ita though it will he observed upon anunderstandingot theinvention that its utility is not to he confinedsolely to the class ot agriculture devoted to the growth oi'l truckpiioduce. y y

lllhile l have designed as a part of my ge* eral machine certain novelearth working devices these form the subject matter et a separateapplication for patent, the improvein'ei'is` hereinafter set forthincluding primarily a novel construction ot wheeled iframe adaptedparticularly forcarrying cultivating tools such as usedfor the purposabove referred to; a special mounting' and relative arrangement of themotor and culriveting," tools, irrespective of the specific'V Vtorni otthe latter, whereby a nicely halanced n implement is ohtainesi relievingthe operator ot abnormal pull or pressure at the handles of the .machine; certain improved controlling' means 'for the motor and 4tor theclutch mechanism, the latterutilized 4for disconnecting; the motor 'fromthe ground wheels in a well# nown manner.; together with novelinstrumcntalitics whereby the ground wheels may he entirely ungearedrelativelvtothe drivinogconnections leading' to the motor .so as tofacilitate the free movement of the implement overthe ground when themotor is rest; and .other improved features oi construction having' todo primarily with-specilic relinements of design.

A period of considerable cxperimentwith machines oli' the `class towhich my invention relates has led me to consider that a motorlcultivator for the purposes of this invention should embody threeyessential characteristics, namely, first-a general design orconstruction as nearly approxiinatina` thatyof ordinary wheeledcoltivatore as it kis poser' yobvious to those skilled in the art.

various desiderata l have accomplished in cated therebeneath f hie torobtain; second-a relative arrangement of the earth working devices andtraetion wheels so as to bring the former as close to the point ot'traction as possible to de crease-to a minimum degree the extent oilateral deiiection of the earth working tools. incident 'to `lateralmovement of the con trollinghandles; and third-an arrangement oi the ymotor cultivating and other parts such will not place upon the operatorundue strains or pressures conducive to quick fatigue? said arrangementbeing furthermore simplified to a maximum degree for purposes These thepractical embodiment of my invention under working conditions. y y For afull comprehension of my improvements including the detailed features ofconstruction and operation, reference is to loe had to the followingdescription and to the accompanying drawings in which Figure l is a sideelevation of a motor cultivator einhodyingthe invention, the near groundwheel omitted to make more clear the illustration; f

'Referring now to the drawings, similar reference characters are appliedto similar parts throughout said drawings, and vcorrespondinglyidentified hereinafter` Frame construction. i

The frame of my machine embodies spaced frame or side members 1connected at a point intermediate their ends with the axle 2 upon whichthe ground wheels 3 are mounted. l effect the axle 2 constitutes afulcrum for the frame or side members 1, and said frame members extendrearwardly from the axle and have bolted or suitably secured thereto thehandles 4: by which the movement of the cultivator is controlled in amanner quite similar to the operation of any common wheeled implement ofthis type. The frame members 1 extend a considerable distance 4forwardfrom the axle 2 and carry at their front ends a fender 5, theextremities of which vextend in front vof the wheels., as shown clearlyin Figure 2f The wheels are ribbed or otherwise'formed on their rims forthe purposev of increa'singtheir tractive effect upon tire groundtraversed thereby, Cross-rods 6. one near the front end of the framemembers 1, another just in rear of the axle 2, and a third connectingthe handles 4. constitute the primary transverse connections between theside elements of the frame.

Motor mel supporting means.

rlhe motor T used by me, generally speaking, may be of a conventionaltype consisting` preferably of a single cylinder engine equipped withsuitable carburetor 8, magneto 9, oil filling' tube 10, fly-wheel 11,and other conventional parts such as the exhaust, valves, sparking'plus'. and incidental parts orlinarilyprovided; but which will not bereferred to because immaterial to the invention. l utilize a peculiarmethod of supporting" themotor however by which there is virtuallyconstituted a counter balance weicht in front of the axle 2, supportedon he frame menbers 1 so as 'to substantially 'Milanoo the earthi'orkincf devices and rertain ther parts arried by the fraine memers lin rear of said axle. lilith the above i view. l have provided on thebase of w engine '7 rearwardlv extending` arms 12 "1 h "'*fh le axlemisses to form a supenfer for said engine.I thus cone rire w"h he franemembers Nmnexhit similar arms 13 i of the engine in a forirecgicti andare connected with the 'ortica of Jhe frame members 1 by nains of asleeve shaft lll suitably bolted in hearinns forried in said framemembers. 'The shaft 14;l has a driven shaft 15 passing theref :hrou gli`said shaft lll forming a part of rieans tobe hereinafter set forth,whereby the driven shaft 15 may be ungeared troni'the 4ground wheelsk 3.

manner in which the engine 7 constitutes a sort of counter; balancevweight will be apparent from the foregoing. The en- ,eine or driving`shaft 16 projects slightly from` the right hand side of the motor crankshaft casing 1'7 and is equipped with a crank pin 18 engageable by thecrank 19 which is ordinarily carried by the right hand handle 1, springclips being attached to the handle to hold the crank 19 in a removablemanner so that the crank may be quickly used when it is desired to turnover the shaft 16 in starting the engine 7. The left hand end of 'thedriving or crank shaft 16 carries the iiywheel 11 previously mentioned,said wheel having an endless belt connection 21 leading upwards to a fanwheel 22 situated so that its blades drive currents of cooling airlaterally against the cylinder of the motor T. The ily-'wheel 11 iskeyed to the drivingshaft 16 aforesaid, as shown best in Fig. 6 andmounted in alignment with the engine shaft 16 is the drive shaft 23. Theshaft virtually abuts at its inner end with the left hand end of theshaft 16. A clutch is used to connect the two shafts 16 and 23.

@luto/zi mechanism.

The fly-wheel 11 is formed with a clutch engage the circular clutchmember 2li which may be made of wood or composition or the like. rl`heclutch member 24 is carried by the annulus 25 which comprises theflanges 25a and 25h. Between the flanges 25il and 251 operate rollerscarried between upper and lower arms of the clutch shifting` yoke 27.rlhe annulus 25 is keyed to the shaft 23 and the coiledspring 28normally presses the annulus laterally in a direction to engage the cluth parts 11l and 24. The yoke 27 is piv- -oed to a bracket plate 29. therear end of which has the axle 2 passing` therethrough and the front endof which has the sleeve shaft lll passing` therethrough. said platebeine; bolted or otherwise attached to the left frame member 1. The lra'iket plate 29 has an upwardly extendine' arm 3() formed with abearing' receiving; the outer end of the shaft said outer end of theshaft carrying a fixed pinion one side of which forms a bearing` for theadjacentend of the spring' 23.

short lateral arm pr-ojectslfroin the fuch yeke and a short rod 33connects said arm with approximately vertical lever 3e nivotefl to theadjacent frame member 1. The upper end of the lever 34 has a rod 35attached thereto which leads back to the left handle el, on the handgrip of which is se- 'ured a casting 36 having the pressure piece 37pivoted thereto. Pressure piece 37 has a downwardly j )rojeftinaarm 38with which the rear end of the rod is connected. I provide a peculiarcontrivance for holding the rod 35 retracted rearwardly to maintain theclutch devices disengaged. This means consists virtuali)7 of atoggle-lever composed of ear link 39 and a front link 40 pivotedrespectively at opposite ends to the parts 38 and the casting 36. r)Chelinks 39 and l0 are vce pivoted together at 4l and the link 39 proiectsvforward beyond the pivot 4l and hasa notch 42 to engage a pin 43 bywhich the upward toggle movement of the links is limited. -l spring 44tired to the casting;` 36

` engages and tends to force downwardly the his engine, the pressurepiece 37 may be pressed and the toggle-lever pushed upwards until itreaches its locking' position shown in Figure in iiill lines.Illherea'liter,y to re- :e the-clutch devices .a slipjht pressure onpart 37 will permit the springl 44 topush downwards on the link-4() andcausethe tog'- gle-lever to break oint and permit the clutch parts toresume cooperative engagement.

The shaft l5 passes through the gear y45 and isequipped on its lett end with thelixed pinion 45.` The eed ot the shaft15k `m'iposite that .carrying the` pinion 46 has a similar pinion-4@ andthe two pinions 46an d 4? are adaptedtomesh with the teeth oft the'large4`(fear rines 48 attached to the ground wheels' b v being bolted orotherwise secured to the spokes oli v said wheels. @bvliouslv thedriving'ot the largo rear 45 on the shattgl, by reason oi' its`connection with the shaft 23, will transmit motion from the shaft 23through the shaft l5 to the .around wheels 8 by reason ott eiiiternieshing' parts 46.477 and 48, A torward or progressive movementoit the ground wheels is thus insured so long as the meshino*l relation.of the gear elements 46, 47., andA .is maintained, and so long theclutch devices are active during engine.

The disengagement olf the "ears-T1w .1 1U., .1r is effecten oy mounting tne einen sha-it i.)eccentrically in the sleeve shait 14. 'l1 hns, when the sleeve shaft 14is turned in one direction. by grasping and torcing i'orvkwardly ahandle 49 iixed to the sleeve. the

.shaft 'l5 will be obviously carried forwards su'iciently` to disengage.the teeth or the pinions4-6 and 47, from the teeth oi the gear rings 48.A reverse or rearward movement' ot the handle v49 turningthe shaflt in alike direction permits olf intermeshing the teeth` of' the gear partsjust mentioned.

Said rearward movement of the handle 49 ymaybe limited by a stop 50extendingfrom th'ebracket plate 29 into the path of the handlerand thesleeve shaft i4 carrying1 the same Araybe locked in such position..namely, with the gear parts intermeshed, byv a vertically movable detentpin 51 mounted on a smallfbracket 52 attached to the upper side ott-hebracket plate 29. 5 The detent pin 5l. is spring' depressed so as tooperate through an opening; in ther'ront end of the bracket plate 29 andengage in an opening in the sleeve shaftl4.

Hydro-carbon supply (md Control means.

The .gasoline or hydro-carbon used by. the engineis supplied byconventional connectionsbetween thehead of the engine and the Agasolinetank 53. i This tank is supported on a U-shaped' standard 54, the lowerends oi"- vv-'hicli are bolted to the frame members l in rear ot theaxle 2. llnclinedy braces `connect the upper ends of the standard 54with the frame members l at points adjacent 'to the lower ends of thehandles 4. Leading; 'romthe gasoline valve arm 56 rearwards is thethrottle rod 57-which terminates atits rear extremity in a loop 58adjacent the handpjrip ofL the right handle 4. The rod 57 passes throughan adjustable stop lever 59 `rotatably mounted .on `the right handle 4.The stop lever 59 may /be moved forwardly or rearwardly, bei formedadjacent its axis with a tubular bearing, one end of which is serratedto engage the serrated portion of a yplate 59a provided with a pin60forming; the axis ot' said lever. .el spring 6l. housed by the pivotedyportion of the lever 59 tends to maintain engagement between theserrated portion ot the lever and the serrated portion et the plate 59a.A Cotter' pin passes through the rod 57 .in rear oit the lever 5.9 andlimits the v'forward movement of the throttle rod, act-ing under thepull of a springa 62 attached to the liront extremity of said rod.Adjustment of the lever 59 forwardly or rearwarddetermines the extent(if-permanent openinglofthe throttle valve of the enginev and isvariable in accordance with varying coniio` ditions of service. The loop58 is pulled whenever desired to accelerate the engine.

Earth wmceag ale/vices.

The earth workin@- or operating devices used in connection iith mycultivator may be of different types dependent of course upon theparticular class of work to be performed. Those which l show maypreferably7 though not necessarily, be employed, and they comprisecultivating` teeth or shovels 68 laterally adjustable in slots 6d ofspaced carriers 65. rl`he carriers 65 each have a forwardly extendingarm 66 pivoted to the frame members 1 by the fastenings which connectthe lower portions of the U- shaped standard 5st with said framemembers 1. The point of pivotal connection of the arms 66 withthe parts1 are designated by 67. For the adjustment of the earth working devices63 l employ a supporting yoke 68, the sides of which are pivotallyconnected at their lower encs with the rear eX- tremities of the arms66. Said sides of the yoke G8 are formed with vertical extensions 69 attheir upper extremities receiving therebetween a lever 70. The lever 70has a series of openings intermediate its ends by which it may beadjustably fulcrumed upon a bracket device disposed between the framemembers 1 at the lower extremities .of the handles fl. The bracketdevice is made in two parts, a U-shaped part 71 bolted to the lefthandle 4l and the double angled part 72 bolted to the right handle 1. A.bolt 7 3 connects these parts 71 and 72 and forms the pivot or fulcrumof the lever 7 0. T he innermost portion of the U-shaped part 71 of thebracket device extends quite a little distance rearwards from the pivot73 and is bent laterally to form a hook 711- beneath which the lever 70may be engaged when pressed rearwardly and downwardly. Obviously arearward and downward pressing of the lever 7 O will raise the yoke 68and the connected earth working devices 63, because the lower end of thelever 70 is attached pivotally to the lowermost one of two bolts orfastenings 75 and 76 by which the side parts of the yoke 68 areconnected together. The arrangement of the bolts 75 and 76 and theformation of a laterally inclined slot 77 in the lower end portion ofthe lever 7 0, just above the opening through which the lower bolt 75passes7 affords a peculiar functioning of the parts in the followingmanner. By disengaging the lever 70 from beneath the hook 74 of thebracket device part 71, and rasing said lever7 the lever and the yoke 68will'be caused to move into substantial alignment. ln matter of fact,the lever will move forwardly toward the gasoline tank 53 slightlybeyond a position of near alignment with the yoke 68 owing to theformation of the slot 77 in the lever, said slot receiving the bolt 76and the latter forming a stop preventing undue forward movement of thelever. llVith the parts thus adjusted the lever 7 O virtually forms alocking member rigidly maintaining the cultivating shovels or earthworking devices at their lowermost adjustment which is their earthworking position, it being required that the `lever 70 be forcedrearwardly to after a manner eifect a break joint action between thepart-s 70 and 68 before the earth working devices can be elevated.

ilfiscelane ous features.

l contemplate the provision of suitable housing` parts 7 S for the gear45 and pinion e6. and possibly other gears and pinions which l use, thisfeature not being material to the invention. Of course suitable greasecups or other lubricating means will be provided for all bearings, wherenecessary.

lt is notable however that the motor and certain'driving connections aredisposed in advance of the axle Q whilst the gasoline tank9 itssupports,v and the earth working devices and other adjacent parts arelocated in rear of said axle. Furthermore, these various parts uponopposite sides of the axle are substantially balanced in an advantageousmanner rendering the operation of the cultivator very easy, owing to thefact that no undue load is placed upon the operator.

Another feature of importance in my construction has to do with thelocation and ar` rangement of the motor and adjacent parts such that lsecure a considerable amount of clearance space between the wheels of myimplement whereby rows of plants to be cu1- tivated may be readilystraddled, and other advantages are resultant, as will be apparent tothose versed in using cultivating devices of the character of theinvention.

Again, by the peculiar disposition of the motor and gear mechanism inadvance of the axle of my implement ll am enabled to connect the earthworking devices to operate very close to the points of tractiveengagement of the ground wheels with the earth. ln this manner l producewhat may be virtually said t0 be a short leverage connection between theearth working devices and the frame of the machine such that slightlateral movement of the frame does not tend to create a large amount oflateral throw of the shovels or teeth or cultivating instrumentalities,whatever they may be.

rjhe general simplicity of my machine is highly conducive to itslightness, strength, and ease of manipulation7 as well as comparativecheapness of construction, all essential requirements of a cultivatoradapted for the purposes of this invention.

By reason of locating the operating means for the ungearng devices atthe front of the implement it Will be apparent that under Wheels so thatthe cultivator will stop, be

ttor-e the gear unmeshing can be ellected. There is noliability,.therefore, of lintermesliing ot the gears While the engine isrunning and operating the driving gearing, which might cause strippingofthe pinions and gears.
